Just find a local caving club, they routinely organise courses for beginners and this is the best way to experience actual caving - you will learn all the proper rope ascent/descent techniques, and if you're into biology you'll have chance to meet all the right people. There's a whole group of biologists doing research in caves - mostly interested in bats, spiders and these crustaceans, and they're always looking for volunteers e.g. for bat counting.
This depends on the water flow in the cave. Plants can't survive any further than daylight reaches, but animals - usually tiny, shrimp-like - are found at the bottom of even very deep caves if o.nly water from surface reaches there, as they are scavenging on organic remains from the surface. Currently the two deepest caves in the world are in Abkhazia - 2200 and 2400 m respectively - and I think these crustaceans have been found there too
I do a lot of caving - mostly exploration and surveying. Most caves aren't such spectacular as seen on the photos but still they are one of the last completely unexplored places in the Earth. This year I had to skip three expeditions due to the pandemics unfortunately 🙄
Some people indeed called to ban Catholic church as a systemically paedophile organisation but I believe it's an unfair generalisation
This is an... interesting point of view, and perhaps the dumbest example of reductio ad hitlerum I've seen for a while 🤦♂️
Rarely I've seen such amount of #bullshit about #history.
We have a long common history that dates back at least to the Roman empire. It's a convoluted history, full of wars and deaths, cultural exchanges and deep genetic mixing between all of the peoples that came and lived here during a few thousands years.
Europe has not been a single nation for long, this is true. But we have a common culture. A culture that learnt to welcome our differences.
A culture that, actually, has been corrupted by the Marshall Plan, but somehow resists in most people here.
Come and see!
You are welcome too! 😉
Did you know that #GDPR allows sites not to announce the use of "essential" cookies? Meaning those your site uses for itself, to keep the user logged in for example.
So when Internet commerce started to slap those stupid "we use cookies" banners on every site they used the more generic word "cookies" to avoid saying outright that their sites use *ad trackers*.
Long story short, if you don't sell your user data, you don't have to present stupid disclaimers.

Американские ученые отслеживали сигналы «мобилок» на военных объектах РФ
Исследовательская группа из Университета штата Миссисипи в рамках научного проекта отслеживала сигналы мобильных телефонов, поступающих с военных объектов в Восточной Европе, пишет The Wall Street Journal.
Ученые, в частности, отслеживали передвижение владельцев сотовых телефонов, находившихся на полигоне ВМФ РФ в Неноксе Архангельской области в августе минувшего года. По данным издания, группа идентифицировала 48 мобильных устройств, находившихся там 9 августа. Позднее часть этих телефонов якобы переместилась в Москву и Санкт-Петербург, а также на закрытые военные объекты в Северодвинске и Архангельске. Кроме того, один из телефонов переместился в Азербайджан, а еще один - на Кубу.
В рамках проекта ученые воспользовались данными GPS из открытых источников, которые фиксируют мобильные приложения потребителей, а потом продают в маркетинговых целях. В проекте использовалась база данных сервиса Locate X платформы Babel Street. Сервис Locate X предоставляет полученные из маркетинговых источников рекламные данные разведслужбам, правоохранительным органам и военным для целей мониторинга. Как отмечает WSJ, в условиях использования сервиса присутствует пункт, согласно которому клиенты не имеют права разглашать существование Locate X.
Представитель подразделения Армии США Эдрик Томпсон (Edric Thompson) подтвердил, что Пентагон финансирует этот проект, поскольку он «обладает хорошим потенциалом применения для обмена информацией между солдатами».
По словам Томпсона, сбор данных о местоположении сотовых телефонов разрешен правилами Армии США в случае, если собираемая информация не включает персональные сведения владельцев мобильных устройств. Он отметил, что исследование ученых также включает анализ «этических и политических последствий» использования таких данных, что поможет военным в будущем.
Can you give some examples? Asking genuinely as a fan, not a protester 😃
sometimes, bacteria just scoop up DNA just floating around minding its own business, and then add it to their own DNA. This is known as horizontal gene transfer, or HGT. It happens all the time, hell, bacteria have been known to occasionally become resistant to some antibiotics by STEALING GENES from OTHER SPECIES of bacteria! The tree of life isn't even a tree! We've done away with that model, it's more accurate to refer to the model as a "braided stream".
And this strange behavior isn't even unique to bacteria, there are examples of plant to plant gene transfer, plant to animal gene transfer, plant to fungus gene transfer, fungus to insect, the list goes on!
basically, the tree of life, when you zoom in close enough, really is a spectrum. The misconception of people who don't understand evolution is partially because the idea of "species" as hard coded boundaries is very natural for us. We love categories and patterns, and unfortunately for us, nature is just not as simple as we'd prefer it to be. Over both space and time, the boundaries between species is blurry. There is no "missing link" because it was always a gradual series of changes to different populations across the world to begin with. The world is a messy and complicated place, and we're all distant cousins of each other.
